Resistance to ozone testing is conducted in-house and is critical to a cable’s performance. Assessment of the deterioration caused by ozone exposure is designed to provide an indication as to how the component will perform over time. Ozone is a naturally occurring substance which erodes compound mixes containing polymers, rubbers, silicones or elastomers.
Cases of unsatisfactory, unsafe or non-compliant materials will often result in cracks or surface breaks, which in operation can lead to serious product failures or problems. Testing enables product designers to revise compound mixes to reduce the impacts of ozone exposure.
Applied to cables such as BS 8592 and the following:
Test Methods & Equipment
ASTM, BS or ISO test methods can be used.
During the testing, samples are placed within the ozone chamber, where concentrated volumes of ozone are released in accordance with the required test standard. The test chamber is used to simulate accelerated assessments of the effects of ozone.
